tcp - How host name is broadcasted in a subnet -

-

i'm working microchip's tcp/ip stack , host name of device not being broadcasted, although can access using dhcp assigned ip.

so question is, protocol network device uses broadcast host name, when see list of devices in network can identify name?

is netbios name service or else? in advance.

the network-agnostic way specify hostname host on network through dns, device cannot control, not lost.

in environments, dhcp , dns servers tied (ad in windows networks, dnsmasq on linux, etc...) best option rely on behaviour. when request ip using dhcp, dhcp protocol allows specify hostname you'd use , if network set allow dns entries created , maintained dns server, hostname send during dhcp request typically used.

the dhcp parameter called 'hostname'. network protocol documentation parameter located in rfc 2132, , explained here.
